Home > E-Tuning
Here at SD Racing we understand that our customers may not be able to dedicate the time needed to travel to our facility for a custom dyno tune. To accommodate your busy schedule we are now offering an E-Tuning solution to fit with your needs. With our years of experience tuning the Subaru EJ and FA engine platforms we can provide you with proper mapping for your engine to give you safe and reliable performance increases.

Mail Order Maps: $250
Our mail order maps are designed for those customers who follow staged upgrade paths, such as Cobb, or for those who mix parts from different manufacturers to suite their needs. These maps do not include any revisions after purchase. If you would like tuning revisions you can upgrade to e-tuning for an additional $100.

  • Stock Turbo Only.
  • Cars must run on 91 or 93 octane.
  • All cars must have a properly working MAF sensor.

E-Tuning: $350
Our E-tuning service is designed for those customers that want a map tailor made for their vehicle. Whether you have minor bolt-on upgrades or a big turbo build, this is as custom as it gets.

  • Wideband O2 sensors installed and calibrated properly.
  • We only work with Deatschwerks, Fuel Injector Clinic, and Injector Dynamics fuel injectors because of their quality and reliability.
